The future of date palm cultivation in the Lower Jordan Valley of the West Bank

Abstract High water consumption and specific soil requirements warrant a long-term planning for date palm cultivation. Hence, this study presents a detailed procedure to calculate water and land balances that assess the suitability for date palm cultivation in three districts of the West Bank. It applies crop response functions to relate spatially explicit land suitability and salinity levels to net revenues. Furthermore, it compares net present values and benefit–cost ratios under various discount rates and salinity levels to assess economic feasibility. Date palm cultivation in Jericho-Al Ghoor is economically achievable, but additional land amendments are required for expansion in Nablus and Tubas districts. Prevailing average salinity levels have minor negative influence on future date palm developments.
